Abstract
The utility model relates to an engine nozzle pressure, injection angle verifying attachment, characterized by support upper and lower position are equipped with cylinder and installation positioning disk respectively, and the upper and lower bottom surface of cylinder has upper and lower oil outlet respectively, and two oil outlet center line slopes in cylinder bottom surface 6 ~ 10, and the installation positioning disk supports on X, Y two-way lead screw, guide pin bushing moving mechanism, and the support of lead screw both ends is on two pairs of gliding sliders of guide rail along the support four sides. The device simulates the oil drop position on the cylinder through adjusting the relative position of the moving mechanism and the cylinder, and checks whether the pressure and the angle of the nozzle are qualified or not according to the condition that the oil beam sprayed by the nozzle passes through the oil hole of the cylinder.
Description
Technical field
The utility model relates to the verifying attachment of engine nozzle injection pressure, angle, belongs to a kind of instruments of inspection of manual adjustment.
Background technique
Along with the extensive use of supercharged engine, the heat load of piston is more and more higher, and nozzle mainly is a kind of device of cooling piston.In order to reach maximum cooling effect and to get out of the way connecting rod, oily Shu Bixu is from certain angle, be sprayed onto on the piston with certain pressure.In the past in design during nozzle, be nozzle to be installed on the body logical high pressure oil verify there is not Special Equipment; Inspection pressure before this during check reexamines angle.Deficiency is:
1, to separate measuring pressure, angle, can not check fast;
2,, adjust trouble for different type of machines;
3, be difficult to accurately check spray angle.
The model utility content
The technical problems to be solved in the utility model provides a kind of nozzle pressure easy to adjust, that check speed is fast, using effect is good, angle of attack verifying attachment operated.
The technical solution of the utility model is: be respectively equipped with cylinder barrel and installing and locating dish at the upper and lower position of the support that has 4 root posts, the upper and lower bottom surface of cylinder barrel has upper and lower oil outlet respectively, the two oil outlet lines of centres favour the cylinder barrel bottom surface, described installing and locating dish is bearing in the two-way leading screw of X, Y, the guide pin bushing mobile mechanism, the leading screw two supports is on two pairs of slide blocks, and slide block slides along the guide rail on support four limits.
Above-mentioned cylinder barrel is installed on the column by sliding sleeve; The upper and lower oil outlet line of centres is 6 °～10 ° with respect to the inclined angle alpha of cylinder barrel bottom surface; The installing and locating dish is provided with locating stud and screw is installed; One end of leading screw has crank.
During use, earlier nozzle is installed on the installing and locating dish, locate by locating stud, by screw, bolton, rotate crank then, adjust two-way leading screw, guide pin bushing mobile mechanism, and the height of adjustment cylinder barrel, make nozzle and cylinder barrel be in the relative position (the oily drop point site on the simulation cylinder) of regulation, whether the high pressure oil of feeding certain pressure in nozzle is qualified from situation check nozzle injection pressure, the angle that the upper and lower oil outlet of cylinder barrel passes through according to the oil bundle again.For the check of the nozzle of different type of machines, can change corresponding cylinder barrel and installing and locating dish.The utility model operation is easy to adjust, and check speed is fast, and using effect is good.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
As figure, cylinder barrel 3 is installed in the top of 4 root posts of support 2 by sliding sleeve 1, and the upper and lower bottom surface of cylinder barrel has last oil outlet A and following oil outlet B respectively, and its aperture is respectively 10mm and 3mm.Upper and lower bottom center is O
